3. ExxonMobil's 'conflict of interest' plan: ExxonMobil(XOM) and its former CEO Rex Tillerson have announced their plan to address concerns about the huge nest egg the oil giant has promised to Tillerson.

Tillerson, who's been nominated as secretary of state by President-elect Donald Trump, is due to receive more than 2 million Exxon shares -- worth more than $181 million at current prices -- over the next decade.

To tackle the ethical and legal problems raised by the massive payout, Exxon said late Tuesday that if Tillerson is confirmed for the high-ranking government job, it plans to put the value of the shares he would have received in an independently managed trust. The trust won't be allowed to invest in the oil company.

Federal law prohibits government employees from taking actions that could affect their personal stock holdings.

4. Fed focus: The U.S. Federal Reserve is scheduled to release the minutes from its important December meeting at 2 p.m. ET. That's the meeting where the Fed raised interest rates for only the second time in a decade.

Wall Street will be scrutinizing the minutes to see whether Fed members talked about the impact of Trump's stimulus plans on future rate hikes.

5. Global market overview:U.S. stock futures are holding steady, indicating that markets will continue trading close to the record-setting levels hit in late 2016.
